2041

Blue

LOCTITE®
Product 2041 is a high fluorescence, low odor, low viscosity single component
anaerobic threadlocking material which develops medium to high strength. The
product cures when confined in the absence of air between close fitting metal
surfaces and is particularly suitable for wicking into preassembled
components. Because of its low viscosity and capillary action, the product
wicks into porosity and eliminates the need to disassemble.

Prevents
loosening and leakage of threaded fasteners. The very low viscosity allows
penetration of the joint by capillary action. The product fills porosity in
welds, castings and powder metal parts.
